Expansion of intranasal betahistine program into mental health supportive care

Initiating project AM-201 for the treatment of histaminergic receptor mediated weight gain and drowsiness in patients treated with antipsychotic medications

Positive scientific advice from EMA on development plan and regulatory pathway for AM-111

Zug, Switzerland, May 15, 2018 - Auris Medical Holding AG (NASDAQ: EARS), a clinical-stage company dedicated to developing therapeutics that address important unmet medical needs in neurotology, today provided a business and strategy update and announced financial results for the first quarter ended March 31, 2018. As part of the strategy update, the Company announced the expansion of its intranasal betahistine AM-125 development program beyond the treatment of vertigo into mental health supportive care indications. Under project code AM-201 the Company will develop intranasal betahistine for the treatment of histaminergic receptor mediated weight gain and drowsiness (somnolence), which are major side effects of many antipsychotic drugs.

"Obesity and related metabolic disorders are major issues in the treatment of mental illnesses like schizophrenia or bipolar disorder, arising largely as adverse side effects from the use of antipsychotic drugs", commented John W. Newcomer, MD, Professor of Integrated Medical Science at the Charles E. Schmidt College of Medicine, Florida Atlantic University, Boca Raton. "Increased rates of diabetes, dyslipidemia, and cardiovascular disease observed in this patient population are known complications of antipsychotic treatment, particularly with those medications that produce the largest adverse effects on body weight. Histamine plays a key role in the brain's regulation of food intake and energy expenditure, and antipsychotic drugs with higher risk for weight gain block histamine H1 receptors - therefore, histamine receptors have become a promising target for modifying antipsychotic-induced weight gain and metabolic risk, with accumulating preclinical and clinical evidence to support this approach."

"We are very excited to launch the development of intranasal betahistine for mental health supportive care indications", stated Thomas Meyer, Auris Medical's founder, Chairman and CEO. "For decades betahistine has been a cornerstone treatment for vertigo in many countries around the world, but its clinical utility has been limited due to the poor bioavailability associated with the oral administration route. Previous clinical research with oral betahistine, which acts as an H1 receptor agonist, also suggested therapeutic benefits in the treatment of antipsychotic induced weight gain. With intranasal delivery we can significantly improve betahistine's bioavailability, which we expect to translate into enhanced treatment outcomes in both indications. We believe that the AM-201 program will be highly synergistic to the AM-125 program and represents a natural extension into an attractive therapeutic area." Auris Medical plans to provide further details on the AM-201 program through a KOL call in early June 2018.

As the Company focuses on advancing its AM-125 and AM-201 programs with intranasal betahistine, it plans to move forward with its late-stage programs AM-111 for the treatment of acute inner ear hearing loss and AM-101 for the treatment of acute inner ear tinnitus through strategic partnering and with non-dilutive funding. In line with this strategy, the Company is reducing the level of operating expenses, which we believe will result in a further and marked reduction of the cash burn rate.

Development Program Updates

AM-125 for Vertigo

Completed oral dosing arm of second Phase 1 clinical trial in healthy volunteers. The first part of the study with administration of escalating doses of oral betahistine up to 384 mg has been completed. Pharmacokinetic data from this part are expected to provide further support for bridging to existing safety data with oral betahistine. In the second part of the study intranasal betahistine will be administered to determine the maximum tolerated dose with single and repeated dosing and generate additional data on bioavailability in humans. An earlier single dose Phase 1 clinical trial with intranasal betahistine up to 40 mg had shown a relative bioavailability which was 20-40 times higher compared with plasma levels in an independent Phase 1 clinical trial with oral betahistine at 3 x 48 mg/day.[1] Results from the second Phase 1 trial are expected to become available in the third quarter of 2018.

Initiated preparations for Phase 2 clinical trial in vertigo. The Company is planning to start a randomized controlled Phase 2 trial in patients suffering from acute surgery-induced vertigo towards the end of 2018. The preparations will include, among others, discussions with health authorities for validation of the study design, additional toxicology testing, as well as further pharmaceutical development work.

Expanded patent estate related to betahistine. The Company acquired two US patents related to the use of betahistine for treating weight gain induced by the antipsychotic drug olanzapine - US patent 7,728,015 "Compositions for weight management" and US patent 7,737,165 ''Methods of reducing weight gain associated with olanzapine treatment".

AM-111 for Acute Inner Ear Hearing Loss

Reported the publication of a peer-reviewed review article entitled "Preclinical and clinical otoprotective applications of cell-penetrating peptide D-JNKI-1 (AM-111)" in Hearing Research, one of the leading journals in the otorhinolaryngology field. The publication reviews AM-111's mechanism of action, pharmacokinetics and therapeutic applications.

Received positive Scientific Advice (Protocol Assistance) from the European Medicines Agency (EMA) related to the development plan and regulatory pathway for AM-111. The Scientific Advice had been requested by the Company following the results of the HEALOS Phase 3 trial. The Agency endorsed the proposed design for a single pivotal trial with AM-111 0.4 mg/mL in patients suffering from acute profound hearing loss design, the choice of efficacy and safety endpoints, as well as the statistical methodology. In addition, the EMA provided important guidance on the regulatory path forward and the maintenance of AM-111's orphan drug designation.

Preparing for FDA consultation. The Company plans to request a Type C meeting with the FDA to discuss the development and regulatory path forward.

Keyzilen® (AM-101) for Acute Inner Ear Tinnitus

Conducted in-depth analyses of full outcomes from the TACTT3 trial. On March 13, 2018 the Company reported that the study did not meet its primary efficacy endpoint of a statistically significant improvement in the Tinnitus Functional Index score from baseline to Day 84 in the active treated group compared to placebo either in the overall population or in the otitis media subpopulation. Further investigation of the trial's outcomes confirmed these preliminary results. The Company believes that the lack of separation between the active- and placebo-treated groups may be due to certain elements of the study design and conduct.

Evaluating next steps with AM-101. Given the strong unmet medical need and in view of the positive data from non-clinical studies, two Phase 2 trials and the two open label AMPACT trials, the Company is assessing measures to address the issues arising in both TACTT trials and how best to advance the program.

Corporate Developments

Regained compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market following a "reverse share split" at a ratio of 10-for-1 of the Company's common shares effectuated through the consummation of the merger with a wholly-owned subsidiary, effective March 13, 2018. At the end of the first quarter 2018 the Company had a total of 6,117,388 common shares outstanding.

Renewed the equity line with Lincoln Park Capital, LLC (LPC). On May 2, 2018, the Company entered into a new equity line for up to $10 million with LPC. The previous equity line with LPC had been terminated upon the Company's merger with one of its subsidiaries in order to effect the reverse share split.

Made an early repayment in April 2018 of $5 million principal amount outstanding under a loan and security agreement with Hercules Capital, Inc. In return, the agreement was amended to remove the liquidity covenant of $5 million. The repayment will reduce the Company's annual interest expense by more than $0.5 million.
